Second-Generation Liquid Platelet Concentrates: A Potential Boon for Regenerative Dentistry

Platelet concentrates have seen significant advancement in the field of biological surgical wound additives. The focus is now on second-generation platelet concentrates, which are completely autologous with no external additives. Unlike other platelet concentrates, liquid or injectable platelet-rich fibrin (i-PRF) is the only one that is obtained in a liquid form. This property widens the horizons for its application to virtually any medical field, including many uses in dentistry. Over the past several years, studies have proposed different variations of i-PRF, such as changes to the protocol by varying centrifugation time, g-force, and other factors. The liquid or injectable form of PRF also allows for other modifications, such as the addition of various biomaterials. This article reviews the current evidence and advancements regarding i-PRF and its potential future applications.
